Bissell Little Green vs Hoover CleanSlate for Pet Stains
The Little Green is the one most owners have lived with; the CleanSlate XL has the better attachments. Neither should be run hot on urine, an instruction neither box gives.

Bissell vs Hoover: the Little Green for pet stains, the XL for tools
Pick by the mess you actually get. For a dog’s accidents on carpet, the Little Green 1400B is the machine owners name for exactly that job; for dried-in stains and embedded hair, the CleanSlate XL’s rubber-spike tool does the scrubbing.
| Machine | Rating | Ratings | The theme in its reports |
|---|---|---|---|
| Little Green 1400B | 4.5 | 94,744 | Pet stains, value; build quality mixed |
| Little Green Mini | 4.5 | 11,270 | Compact, easy; suction mixed |
| CleanSlate Plus | 4.3 | 11,564 | Suction praised; hose breaks |
| CleanSlate XL | 4.5 | 895 | Attachments, storage; newer listing |
The 1400B is an old design with a long tail of owners, and what they keep reporting is puppy spots lifted out of light carpet. The CleanSlate Plus is the one to skip, because its recurring complaint is the hose.
Neither should be run hot on urine
Humane World’s guidance is explicit, and no box here repeats it: avoid steam cleaners on urine, because the heat permanently sets the stain and the odour by bonding the protein into man-made fibres.
Portable extractors are not steam cleaners, but some offer a heated mode and all of them accept hot tap water. On a urine stain, fill the Little Green or the CleanSlate with cool water. Save heat for grease and coffee.
Bissell: the deep record, and the small one
BISSELL Little Green Multi-Purpose Portable Carpet Cleaner, 1400B
94,744 ratings at 4.5, with owners naming puppy accidents on light carpet as the job it handles.
Current price shown on Amazon. We may earn a commission.
| Owners praise | Pet stains, small cleanups |
|---|---|
| Mixed reports | Build quality |
| Record | 94,744 ratings |
Owners describe it working on small cleanups and pet stains specifically, one naming puppy spots on white carpet, and most calling it worth the money against a professional visit.
Build quality is where reports divide, which is what you would expect of a design this widely sold and this long on the market. Nothing in the reports touches the extraction itself.
Buy it if
- You want the machine the most owners have actually lived with
Don't buy it if
- You want the newest attachments rather than the proven body
BISSELL Little Green Mini Portable Carpet Cleaner, 4075
The compact version owners buy for pet messes, cheaper than calling a cleaner and small enough to leave out.
Current price shown on Amazon. We may earn a commission.
| Size | Mini body |
|---|---|
| Owners praise | Compact, easy, pet messes |
| Mixed reports | Suction |
The Mini is the same idea in a smaller body: 4.5 across 11,270 ratings, bought for pet messes and praised for being easy and compact enough to leave within reach.
Suction draws the mixed notes. For a dog that has an accident in one spot, that trade is usually fine; for a whole rug, buy the full-size 1400B above.
Buy it if
- Your messes are small and frequent rather than large
Don't buy it if
- You are extracting a whole rug after a sick dog
Hoover: better tools on one model, a hose problem on the other
Hoover CleanSlate XL Carpet + Upholstery Spot Cleaner
A traditional brush plus a rubber-spike scrubbing tool, in a body owners say still fits a closet.
Current price shown on Amazon. We may earn a commission.
| Attachments | Brush and rubber-spike tool |
|---|---|
| Owners praise | Suction, storage size |
| Record | 895 ratings, newer listing |
The XL is the best-equipped machine here. Owners single out the attachments, a traditional brush plus a rubber-spike scrubbing tool, and say it still stores in a closet.
It is a newer listing with few reviews yet, so buy it for the tools rather than the reputation. It earns its place if dried-in stains and embedded hair are your problem.
Buy it if
- You are scrubbing embedded hair and dried stains
Don't buy it if
- You want a long owner record behind the purchase
Hoover CleanSlate Plus Carpet + Upholstery Spot Cleaner
Strong suction by owner reports, undermined by the hose failing with regular use and a spray nozzle owners complain about.
Current price shown on Amazon. We may earn a commission.
| Owners praise | Suction on spills |
|---|---|
| Owners report | Hose breaking in use |
| Owners report | Spray nozzle problems |
Owners rate the suction highly and call it effective on spills. The reason it sits lowest here at 4.3 is specific rather than vague: the hose breaks with regular use, and the spray nozzle draws its own complaints.
A hose is not a part you improvise around mid-clean. If you buy it, keep the receipt and register the warranty on the day it arrives.
Buy it if
- You want Hoover's suction and will register the warranty
Don't buy it if
- The hose is the part you cannot work around
What to do with the machine after the mess
Extract, then treat the smell. A machine lifts the liquid; it does not break down the compounds that make a dog return to the same patch. That is what an enzyme cleaner does, worked in after the machine has lifted the liquid.
The order matters, and so does what you skip: no ammonia, no vinegar, no heat. Getting dog urine out of carpet sets out the full sequence, and what a dog coat has to do covers the other winter purchase for a dog in the house. To see both against Shark’s StainStriker, portable carpet cleaners, compared ranks 6.
